Participants

Reaction Steps

6 ml of pyridine, 1 g of N-[3-(dimethylamino)propyl]-N′-ethylcarbodiimide hydrochloride and 1 g of methyl 3-amino-2-hydroxybenzoate are added to a solution of 1 g of [4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetate prepared in stage 2 of example 1, in 6 ml of N,N-dimethylformamide. The reaction mixture is stirred at ambient temperature for 15 hours, and then concentrated under reduced pressure. Water and ethyl acetate are added and the resulting mixture is thus stirred for 30 minutes. The precipitate formed is filtered off, and rinsed with water, ethyl ether and petroleum ether. The solid obtained is dried under vacuum. 1.27 g of methyl 2-hydroxy-3-({[4-(morpholin-4-yl)-6-oxo-1,6-dihydropyrimidin-2-yl]acetyl}amino)benzoate are obtained in the form of a grey solid, the characteristics of which are the following:
